I don't need hours. I need minutes. That how long it takes to sell a bunch of shorts and buy some longs.
I am not man enough to do short speculation in this market. Perhaps going speculatively long is my way to go, or just forget about it until there is low-hanging shortable fruit at $7k...
Meanwhile, while we go to 270 and maybe below, your idea of "buying all the bitcoins" is exactly what we don't need. We need more bitcoins in the hands of more people, not less.
When the price goes down, the ownership concentrates (manipulator/whale accumulation, large speculator buying). It's during the booms that new people buy trickles and coins are dispersed. Both are good to keep the coins in the hands that value them the most.
